• B)a = (−7.2)+ (4.3t)
• C)a = (5.3t)+ (12.9t²)
• D)a = (−7.2)+ (8.6t)
• E)a = (−14.4t)+ (4.3t²)

Alternative RNA Splicing

A post-transcriptional process in which exons or introns are selectively included in or excluded from a final mRNA transcript, thus allowing a single gene to code for multiple proteins.

Acetyl Groups

Functional groups in organic chemistry that consist of a methyl group single-bonded to a carbonyl. The formula is CH3CO-.

Methyl Groups

Chemical groups consisting of one carbon atom bonded to three hydrogen atoms, often involved in modifying DNA or proteins in cells.
